Until then, training programs varied greatly in length and in the subjects covered. The ASXT presented its first standardized curriculum in 1952. It described a one-year course in x-ray technology and recommended the number of hours that should be devoted to each subject, ranging from physics and anatomy to positioning and darkroom technique.
Megavolt X-ray (or photon) therapy, which delivered a beam of 25 MeV X-ray photons. The X-ray photons are produced by colliding a high current, narrow beam of electrons with a tungsten target. The X-rays are then passed through a flattening filter, and then measured using an X-ray ion chamber. The flattening filter resembles an inverted ice ...
Izanagi and Izanami, realizing that they were meant to procreate and have children, then devised a marriage ceremony whereby they would walk in opposite directions around the pillar, greet each other and initiate intercourse. After Izanami greeted Izanagi first, Izanagi objected that he, the man, should have been the first to speak.
Chihaya Adachi (born 26 October 1963) is a Japan-born scientist and lecturer specializing in organic electronics which is a field of materials science.Adachi is the Director of the Center for Organic Photonics and Electronics Research (OPERA) at Kyushu University, [1] a large multi-disciplinary team of physicists, chemists, and engineers from both academia and industry.
The Institute of X-Ray Engineers was formed in 1944 in Liverpool, [1] soon after changing its name to the Society of X-Ray Technology. In the mid-1980s it was one of 51 societies in the new Engineering Council, in group four.
The Herculaneum papyri that survived the Vesuvius disaster were excavated and researchers have used X-rays to read their contents. Previous methods involved slowly unrolling the papyrus, which damaged much of the scrolls, some beyond repair. [29] X-ray technology was used to quickly identify individual coins uncovered in a single container ...

Muon tomography is a technique that uses cosmic ray muons to generate three-dimensional images of volumes using information contained in the Coulomb scattering of the muons. Since muons are much more deeply penetrating than X-rays, muon tomography can be used to image through much thicker material than x-ray based tomography such as CT scanning.
